Communication with the host microcontroller runs over an I²C interface, making it a straightforward addition to existing battery-management buses.
It remains a current-production choice for new designs.
The 2.5x4 mm body suits space-constrained battery packs. Cut Tape works for prototyping and low-volume runs.
It uses the Impedance Track algorithm, which measures the battery's internal impedance along with voltage and current to compute state-of-charge. This method compensates for load variation and temperature drift, giving a more reliable fuel-gauge reading than simple voltage lookup.
No. The part is designed for single-cell Lithium Ion packs only. A 2-cell stack would exceed the input range of the monitor.
The I²C address is set internally and is documented in the device datasheet. It is a fixed address — no external address pins are provided on this package.
